ABSTRACT

A package for a particulate laundry scent additive.

FIELD OF THE INVENTION

A package for a particulate laundry scent additive.

BACKGROUND OF THE INVENTION

Many consumers like to enhance the scent of their laundry using variousproducts such as scented detergents, scented sheet or liquid fabricsofteners, and additives to the wash. Packaging for laundry productsmust be robust enough to protect the packaging and the contents thereinfrom damage from the time that the product is placed in the package towhen the product is used by the consumer in her home. A common approachto packaging is to make every practical effort to isolate the product inthe package from the external environment.

Particulate laundry scent additives can be applied to the wash using adosing cup that is provided with the packaging. The dosing cup can besnapped onto a closure for the container that houses the particulatelaundry scent additive. For instance, the container can be a generallycylindrically shaped bottle having an open end, the bottle being sizedand dimensioned to be conveniently gripped by the user as she pours theparticulate laundry scent additive from the container. A closure, suchas a common screw in cap, can be threadably engaged with the open end ofthe bottle to prevent the contents of the container from spilling out. Adosing cup can be peripherally snapped to the closure so as to be in aconvenient location when the consumer uses the product.

There are at least three problems associated with such a packagingdesign. First, the dosing cup may become separated from the threadedclosure during shipping or while being displayed on a shelf in a retailenvironment or while stored in the consumer's home. These two packagingcomponents might become separated as a result of the package beingdropped during handling or by a person intentionally removing the dosingcup from the closure. If a consumer arrives at the shelf from which sheselects the product and does not recognize that the dosing cup ismissing from the package, she may purchase an incomplete product and maynot be able to fully enjoy the benefits from using the product. Anotherresult of a missing dosing cup might be that the retailer may choose topull the product from the shelf because of the inability of the retailerto sell the product, which is a financial loss to the retailer or aparty further up the supply chain for the product.

A second problem with the packaging design outlined above is that theconsumer might be tempted to open up the closure to smell the product tomake sure the scent is desirable to her. Such behavior can result inproduct being spilled or otherwise exposed to the environment.

A third problem with the packaging design outlined above is that theconsumer may be required to handle three separate elements when shedispenses the product, the container, the closure, and the dosing cup,with only two hands, which can be inconvenient.

In view of these problems, there is a continuing unaddressed need forpackaging for a laundry scent additive that includes a container, aclosure, and a dosing cup that is robust enough to endure rough handlingwithout the dosing cup becoming separated from the closure yet providesthe consumer with an opportunity to experience the scent of the productat shelf without opening the packaging and can be conveniently deliveredto the laundry with only two hands.

SUMMARY OF THE INVENTION

A package comprising: a container, the container having an open end andcontaining a particulate laundry scent additive, the laundry scentadditive comprising free perfume; a closure engaged with an open end ofthe container, the closure having a peripherally recessed portion; adosing cup comprising a closed end, a peripheral rim, and a wallextending from the closed end to the peripheral rim to define a dosingvolume, the dosing volume in fluid communication with the peripherallyrecessed portion of the closure, the peripheral rim releasably engagedwith the closure, the dosing cup having a longitudinal axis, at least aportion of said dosing volume extending further away from thelongitudinal centerline than at least a portion of the peripherallyrecessed portion of the closure, the wall comprising a tapered portioninwardly tapered towards the longitudinal axis, wherein the dosing cupcomprises a vent opening in the closed end or in the wall, wherein thevent opening is sized and dimensioned to retain the particulate laundryscent additive; and a shrink sleeve wrapping around the container andthe closure and at least a portion of the tapered portion of the dosingcup wall thereby providing a redundant mechanism of engagement betweenthe dosing cup and the container, wherein the vent opening isunobstructed by the shrink sleeve, wherein the shrink sleeve bridgesover at least a portion of the peripherally recessed portion of saidclosure.

DETAILED DESCRIPTION OF THE INVENTION

A package 5 for a laundry scent additive 40 is shown in FIG. 1. Thepackage 5 can comprise a container 10, a closure 20, a dosing cup 30,and a shrink sleeve that wraps around the container 10, the closure 20,and at least part of the dosing cup 30. The container 10 can be a blowmolded plastic bottle made of polyethylene terephthalate or any othermaterial having the capability of being robust during transport anddisplay, including other plastics and paper. The container 10 can beflexible enough such that the container 10 is deformable to a personsqueezing the bottle with her hand. The container 10 can have an openend 110 through which the contents of the container 10 can be poured bythe consumer.

The container 10 can comprise polyethylene terephthalate and can have awall thickness of about 0.254 mm. The container 10 can be a generallycylindrical bottle having a height of about 198 mm and a diameter ofabout 76.2 mm. The container 10 can be generally tapered at mid-heightto provide a location on the container 10 that is sized and dimensionedto be gripped by an adult woman. The container 10 can be the bottle thatis used for the 26 ounce size of TIDE STAIN RELEASE, marketed by TheProcter & Gamble Company, Cincinnati, Ohio, as of Oct. 1, 2010.

The container 10 can contain a particulate laundry scent additive 40such as that disclosed in U.S. patent application Ser. No. 12/732,576 orany other particulate scented product that can be applied with a dosingcup 30. The particulate laundry scent additive 40 can be a compositionthat is added into the tub of a washing machine before or during a washcycle. The particulate laundry scent additive 40 can comprise a materialselected from the group consisting of a surfactant, a fabric softener,perfume microcapsules, a perfume, and combinations thereof. Theparticulate laundry scent additive 40 can be a granular detergent suchas any variant of TIDE, marketed by The Procter & Gamble Co.,Cincinnati, Ohio, USA, as of Oct. 1, 2010.

The closure 20 can be engaged with the open end of the container 10. Theclosure 20 can serve to enclose the laundry scent additive 40 within thecontainer 10 such that particles of the laundry scent additive 40 cannotspill out of the container 10 when the closure 20 is engaged with thecontainer 10. The closure 20 can be a flip top cap 120 having aperipherally recessed portion 130. The peripherally recessed portion 130can be sized and dimensioned to allow the consumer to get at least partof the end of one of her fingers partially under the edge 122 of theflip top cap 120 or under a lift tab protruding from the flip top cap120 such that she can pry open the flip top cap 120.

After removing the dosing cup 30 from the package 5 and placing thedosing cup 30 in an upright position in her free hand or on a suitableflat surface, the flip top cap 120 can be opened. Once the flip top cap120 is opened, the consumer can pour the particulate laundry scentadditive 40 into the dosing cup 30 that can be held in one of theconsumer's hands or resting on a flat surface. The flip top cap 120 canbe a separate or integral part of the closure 20 in which the body ofthe closure 20 and the flip top cap 120 are connected to one another bya hinge, such as a simple hinge or a butterfly hinge that is bi-stable.The flip top cap 120 can have a spud. The spud of the flip top cap 120can engage with an orifice in the body of the closure 20. The flip topcap 120 can comprise polypropylene.

The dosing cup 30 can comprise a closed end 50, a peripheral rim 60, anda wall 70 extending from the closed end 50 to the peripheral rim 60 todefine dosing volume 32. The dosing volume 32 can be between about 10 mLand about 80 mL and can have a generally fustro conical shape,discounting for any decorative features of the shape of the dosing cup30. The peripheral rim 60 can be releasably engaged with the closure 20.The dosing cup 30 can be engaged to the closure 20 by snapping theperipheral rim 60 of the dosing cup 30 to the closure 20. For example,the closure 20 can have a lip 21 to which the peripheral rim 60 can befrictionally engaged. The diameter of the part of the inner part of thelip 21 can be slightly larger than the diameter of the inner edge of theperipheral rim 60 such that the inner edge of the peripheral rim 60 fitstightly to the lip 21. The dosing cup 30 can engage with the closure 20using a tongue and groove fitting. The dosing cup 30 can engage with theclosure 20 via a constrained hoop in which the peripheral rim 60 of thedosing cup 30 is circumferentially constrained and under circumferentialcompression in a direction along the peripheral rim 60, much like theway a large cap is engaged with a typical foam shaving cream container.

The dosing cup 30 can have a longitudinal axis L. The longitudinal axisL can be considered to extend through the closure 20 and the container10. The wall 70 can comprise a tapered portion 80 that is inwardlytapered towards the longitudinal axis L. The dosing cup 30 can begenerally fustro conically shaped with the broadest dimension at theopen end of the dosing cup 30 defined by the peripheral rim 60 and thenarrowest dimension near or at the closed end 50 of the dosing cup 30.The inwardly tapered portion 80 can be adjacent the peripheral rim 60.

The dosing volume 32 can be in fluid communication with the peripherallyrecessed portion 130 of the closure 20. One way to relate the dosing cup30 and closure 20 in such a manner is to structure the dosing cup 30such that at least a portion of the dosing volume 32 extends furtheraway from the longitudinal axis L than at least a portion of theperipherally recessed portion 130 of the closure 20. The objective ofproviding such a relationship between the dosing volume 32 andperipherally recessed portion 130 of the closure is to provide a conduitfor movement of perfumed air that is driven from the container 10 to theperipherally recessed portion 130 of the closure 20, through the dosingvolume 32, and out the vent opening 100 to the consumer's nose.

FIG. 2 schematically illustrates an embodiment of an arrangement of adosing cup 30 and a closure 20. The closure 20 illustrated in FIG. 2 hasa flip top cap 120. In FIG. 2, the dosing cup 30 is illustrated in crosssection and the closure is shown in side view to reveal how the dosingcup 30 and dosing volume 32 can relate to the peripherally recessedportion 130 of the closure 20. As shown in FIG. 2, the dosing cup volume32 is in fluid communication with the peripherally recessed portion 130of the closure 20.

By having the dosing cup 30 inwardly tapered adjacent the peripheral rim60, a shrink sleeve that is applied to the package 5 over the container10, closure 20, and the inwardly tapered portion 80 of the dosing cup30, can help to secure the dosing cup 30 to the container 10 such thatthe dosing cup 30 does not become unintentionally disengaged from thecontainer 10 prior to the consumer first using the particulate laundryscent additive 40. The dosing cup 30 can comprise polypropylene.

The dosing cup 30 can comprise a vent opening 100 in the closed end 50or wall 70 of the dosing cup 30. The vent opening 100 can serve as aconduit for perfumed air to be expelled from the container 10 towardsthe consumer's nose. For instance, at the point of purchase, theconsumer may desire to experience the scent of the laundry scentadditive 40 to make sure she is pleased by the scent. The consumer cansqueeze the container 10, which will expel a small quantity of perfumedair through the open end 110 of the container 10, through the orifice ofthe closure 20, possibly via the interface between the spud 24 and theorifice 23, through the peripherally recessed portion 130 of the closure20, into the dosing volume 32 of the dosing cup 30, and through the ventopening 100, which will allow the consumer to smell the laundry scentadditive 40 in the container 10 without having to open the package 5.Given the sensitivity of a typical consumer's nose, only a small volumeof perfumed air, or mass of perfume, need be expelled out the ventopening 100 for the consumer to sufficiently experience the scent of thelaundry sent additive 40.

The perfumed air in the container 10 can reside in the interstitialspaces between particles of the laundry scent additive 40 and in anyheadspace within the container 10. The scent may be provided by perfumethat diffuses out of the particles of the particulate laundry scentadditive 40. The perfume can be free perfume within the particles oflaundry scent additive 40 or perfume from ruptured perfume microcapsuleswithin the laundry scent additive 40.

The vent opening 100 can be sized and dimensioned to retain theparticulate laundry scent additive 40. The vent opening 100 can be sizedand dimensioned to retain 100% of the particles of a unit dose of theparticulate laundry scent additive 40. Such a relationship in sizebetween the vent opening 100 and size of the particles of theparticulate laundry scent additive 40 can be helpful for avoidingspilling of the laundry scent additive 40 through the vent opening 100when a unit dose of the laundry scent additive 40 is poured into thedosing cup 30. The vent opening 100 can be a small slot 0.75 mm wide by2 mm in length. The vent opening 100 can be a small circular aperturehaving a diameter between about 0.5 mm and about 3 mm. The vent openingcan be a small slot having a length between about 0.5 mm and about 3 mmand a width between about 0.5 mm and about 3 mm. The vent opening 100can be an aperture molded in the dosing cup 30 or can be an aperturethat is formed in the closed end 50 of the dosing cup 30 after moldingof the dosing cup 30. The dosing cup 30 can comprise one or more ventopenings 100. The vent opening 100 can have the shape of a rectangle andhave dimensions of about 39 μm by about 79 μm. The particulate laundryscent additive 40 can be generally spheroid shaped having a diameterbetween about 4 mm and about 6 mm and an aspect ratio of height todiameter of between about 0.35 and about 0.6. The particulate laundryscent additive 40 can be generally spheroid shaped having a diameter ofabout 5 mm and an aspect ratio of height to diameter of about 0.5.

A schematic of a closure 20 in an open position is shown in FIG. 3. Asshown in FIG. 3, the closure 20 can comprise a body 22, a peripherallyrecessed portion 130, and a flip top cap 120 connected to the body 22.The flip top cap 120 can have a portion that is sized and dimensioned toreleasably lock into place in the orifice 23 of the body of the closure20 or the body of the closure 20 itself. A spud 24 can extend from theunderside of the flip top cap 120 that is sized and dimensioned toreleasably lock, for instance by friction or a tongue and groove, intothe orifice 23 of the body so that purposeful effort must be exerted bythe consumer to open the closure 20 by flipping open the flip top cap120. The fit of the spud 24 into the orifice 23 can be sized anddimensioned such that at least some airflow is possible at low pressureat the interface between the spud 24 and the orifice 23 yet the spaceproviding for airflow is sized and dimensioned such that particles ofthe laundry scent additive 40 cannot fit into the space at the interfacebetween the spud 24 and the orifice 23. The closure 20 can be threadablyengaged with the container 10 using a threaded connection, such ascomplementary threads on the closure 20 and the open end 110 of thecontainer 10.

Closure 20 can be a cap such as that shown in FIG. 4. Closure 20 canscrew or snap onto or into container 10. The peripherally recessedportion 130 of closure 20 can extend along the entire height of theclosure 20, the height being considered parallel with the longitudinalaxis L of the dosing cup 30 when the dosing cup 30 is engaged with theclosure 20. The peripherally recessed portion 130 of closure 20 canextend along at least an upper portion of the height of the closure 20.A cross section of the closure 20 shown in FIG. 4 is shown in FIG. 5.

The package 5 can comprise a shrink sleeve 90 that wraps around thecontainer 10 and the closure 20 and at least a portion of the taperedportion 80 of the dosing cup 30, as shown in FIG. 6. Suitable shrinksleeves can be formed from, for example, but not limited to, polyvinylchloride, polyethylene terephthalate with glycol, poly lactic acid—cornbased biopolymer such as EARTHFIRST material, oriented polystyrene, orother material known in the art and employed as a shrink sleeve. Theshrink sleeve 90 can bridge over at least a portion of the peripherallyrecessed portion 130 of the closure 20. Such bridging can leave adefined void space between the peripherally recessed portion 130 of theclosure 30 and the wall 70 or tapered portion 80 of the dosing cup 30. Adefined void space at the location of the peripherally recessed portion130 may help improve the fluid communication between the peripherallyrecessed portion 130 and the dosing volume 32 and ultimately to theconsumers nose. The shrink sleeve 90 can be polyethylene terephthalate,oriented polystyrene, or polylactic acid or other material commonly usedfor shrink sleeves. The shrink sleeve 90 can be the same material asused for the shrink sleeve provided in the 26 ounce package of TIDESTAIN RELEASE, marketed by The Procter & Gamble Company, as of Oct. 1,2010.

The shrink sleeve 90 can provide a redundant mechanism of engagementbetween the dosing cup 30 and the container 10. In absence of a shrinksleeve 90, the dosing cup 30 is engaged to the closure 20 and theclosure 20 is engaged with the container 10, thereby effectivelyengaging the dosing cup 30 with the container 10. In such an embodiment,the marketer is depending on the integrity of the mechanism ofengagement between the dosing cup 30 and the closure 20 to keep thedosing cup 30 from being prematurely or unintentionally separated fromthe closure 20. If the package 10 is dropped by the person stocking theshelf display, a person shopping for the package 10, or knocked from theshelf, the impact may dislodge the dosing cup 30 from the closure 20. Ifsuch an event happens, the dosing cup 30 may be damaged or lost. Adamaged or lost dosing cup 30 might be dissatisfying to a consumer, theretailer, and the marketer of the package 5.

The shrink sleeve 90 can closely conform to the contour of the container10, closure 20, and at least a portion of the tapered portion 80 of thedosing cup 30. By having the shrink sleeve 90 extend over at least aportion of the tapered portion 80 of the dosing cup 30, the shrinksleeve can help restrain the dosing cup 30 from becoming disengaged withthe closure 20 by applying an additional longitudinally directed forceacting to assist in maintaining engagement between the dosing cup 30 andthe closure 20. Further, by employing a tapered dosing cup 30, themaximum dimension of the dosing cup 30 proximal the peripheral rim 60can be larger than the opening in the shrink sleeve 90 near the top ofthe package 5. Structured as such, considerable force may be requireddislodge the dosing cup 30 from the rim 60 and through the open end ofthe shrink sleeve 90 at the top of the package 5. The fit of the shrinksleeve 90 to the container 10, closure 29, and portion of the taperedportion 80 of the dosing cup 30 can be the same as the fit of the shrinksleeve to the container in TIDE STAIN RELEASE, marketed by The Procter &Gamble Company, Cincinnati, Ohio, as of Oct. 1, 2010.

The shrink sleeve 90 can be sized and dimensioned such that at least aportion of the closed end 50 or wall 70 is revealed to the consumer. Bydesigning the shrink sleeve 90 as such, the vent opening 100 can beunobstructed by the shrink sleeve 90. This arrangement can provide for acontinuous pathway for air-flow communication, from within the container10 to the consumer's nose, through which scent can be transported fromwithin the container 10 to the consumer's nose. The shrink sleeve 90 canbridge over the peripherally recessed portion 130 of the closure 20.

With a shrink sleeve 90 in place, as described herein, when the consumersqueezes the container 10, a small quantity of perfumed air is expelledthrough the open end 110 of the container 10, through the orifice 23 ofthe closure 20, through the peripherally recessed portion 130 of theclosure 10 in a conduit defined by the recessed portion 130 and theshrink sleeve 90 bridging over the recessed portion 130, through thedosing volume 32 and out the vent opening 100 to the consumer's nose.The shrink sleeve 90 need not perfectly seal around the dosing cup 30,closure 20, and container 10. Rather, the degree of such seal need onlybe to a conformity sufficient to result in some of the perfumed airexpelled through the open end 110 of the container exiting the package 5through the vent opening 100 and to provide support for preventing thedosing cup 30 from being prematurely separated from the closure 20.Thus, the shrink sleeve 90 can be imperfectly sealed around the dosingcup 30, closure 20, and container 10. Whether or not some of theperfumed air expelled from the container 10 escapes via pathways otherthan the vent hole 100 is not critical because of how it is thought thatconsumers will perceive the package 5 disclosed herein. It is thoughtthat the consumer will naturally choose, or be instructed to choose byuser instructions located on the shrink sleeve 90 or via some otherinstruction, to smell the contents of the package 5 through the venthole 100, rather than through any imperfection in the seal between theshrink sleeve 90 and the dosing cup 30, because consumers may likely notexpect to be able to experience the scent of the contents of the package5 at a location other than the vent hole 100.

A consumer can sample the scent from the package 5 disclosed hereinfollowing a method comprising the steps of squeezing the container 10 toexpel perfumed air from the container 10 through the vent opening 100and smelling the perfumed air.

In one embodiment about 4 ng to about 8 ng of perfume can be expelledfrom the package 5 when the container 10 is squeezed by hand to expelbetween about 0.6 mL and about 0.9 mL of perfumed air from within thecontainer 10.

In one embodiment the vent hole 100 can be at or near the closed end 50of the dosing cup 30. This arrangement might be practical in that if aconsumer squeezes the container 10 with the container in the uprightposition, the location of the vent hole may be conveniently located forthe consumer to place immediately beneath her nose so that she caneasily detect the scent of the particulate laundry scent additive 80.

The consumer can squeeze the container 10, which will expel a smallquantity of perfumed air through the open end 110 of the container 10,through the orifice of the closure 20, possibly via the interfacebetween the spud 24, if present, and the orifice 23, through theperipherally recessed portion 130 of the closure 20, into the dosingvolume 32 of the dosing cup 30, and through the vent opening 100, whichcan allow the consumer to smell the particulate laundry scent additive40 in the container 10 without having to open the package 5. Given thesensitivity of a typical consumer's nose, only a small volume ofperfumed air need be expelled out a vent opening 100 for the consumer toexperience the scent of the particulate laundry sent additive 40.Closure 20 may only need to leak a small amount of perfumed air toprovide a detectable scent to the consumer. Leakiness can be provided ina flip top cap 120 by molding the flip top cap 120 such that theelements of the cap do not fit together in an air-tight manner for therange of pressure that can be developed in the container 10 by a humanhand squeezing the container 10. Similarly, leakiness in a threadedclosure 20 can be provided using loose complementary threads that do notfit together in an air-tight manner for the range of pressure that canbe developed in the container 10 by a human hand squeezing the container10.

As shown in FIG. 6, the shrink sleeve 90 can comprise a line of weakness110 extending at least partially around one or more of the closure 20,the container 10, and the interface between the closure 20 and thecontainer 10. The line of weakness 10 can facilitate the consumertearing away a portion of the shrink sleeve 90 to free the dosing cup 30from the package 5 and accessing the particulate laundry scent additive40 in the container 10.

If the line of weakness 110 extends at least partially around one of thecontainer 10, closure 20, and the interface between the closure 20 andthe container 10, when the consumer tears away the portion of the shrinksleeve 90 above the line of weakness 110, she will expose the closure 20and the dosing cup 30. This will present the dosing cup 30 to theconsumer so that she may disengage the dosing cup 30 and she will havethe option of removing the closure 20 or opening the flip top cap 120 todispense the particulate laundry scent additive 40 from the container 10and into the dosing cup 30.

If the line of weakness 110 extends at least partially around theclosure 20 or extends at least partially around an interface between theclosure 20 and the container 10, when the consumer tears away theportion of the shrink sleeve 90 above the line of weakness 110, she willexpose a portion of the closure 20 and might expose peripherallyrecessed portion 130 of the closure 20. An arrangement in which the lineof weakness 110 is between the peripherally recessed portion 130 of theclosure and the container 10 can be practical in that the shrink sleeve90 can obscure the interface between the closure 20 and container 10. Byobscuring this interface, the consumer might employ the closure 20 asdesired, for instance by using a flip top cap 120, if provided, ratherthan removing the closure 20, possibly by unscrewing or unsnapping, todispense the particulate laundry scent additive 40.

The line of weakness 110 in the shrink sleeve 90 can comprise anystructure that renders the shrink sleeve 90 to be frangible along theline of weakness 110. The line of weakness 110 can be perforated. Theline of weakness 110 can be a structurally weakened portion of theshrink sleeve 90. The line of weakness 110 can comprise a series ofperforations or indentations that selectively weaken a portion of theshrink sleeve 90.

The mass of perfume that can be expelled by a consumer squeezing thepackage 5 is characterized by the Perfume Expulsion Test Method. Aschematic of the set up for the Perfume Expulsion Test method is shownin FIG. 7. A 2 L Tedlar bag 200 (Supelco part #24654) is used to captureperfume that is expelled from the vent opening 100 or vent openings 100of the dosing cup 30. The bottom portion of the Tedlar bag 200 isremoved leaving the top portion that has the locking adapter 210. Thetop portion of the Tedlar bag 200 is sealed to the dosing cup at alocation above the shrink sleeve 90 using O-rings such that the Tedlarbag 200 captures perfumed air that is expelled from the vent opening 100or vent openings 100 of the dosing cup 30 when the container 10 issqueezed. A trap 220 having Tenax-TA 35/60 (Restek cat #25701) isattached to the locking adapter 210.

The container 10 is supported to a height of at least 68 mm with animpression mold 230 that conforms to the contour of the side of thecontainer 10 that is oriented away from the direction from which thesqueezing force is applied and is restrained in the direction in whichthe squeezing force is applied. The impression mold is solid urethane.The height is measured from the portion of the container 10 designed torest on a surface when the container is displayed to a consumer. Thecontainer 10 is laterally restrained at the bottom of the container 10such that when the squeezing force is applied, the container 10 does notmove laterally relative to the direction from which the squeezing forceis applied.

A squeezing force of at least 41.5 N is applied to the container 68 mmfrom the bottom of the container 10 for 5+/−2 seconds. The squeezingforce is applied by a loading piston 240 having the dimensions of anOmega 1 inch load cell (LC304-100) or such load cell itself acting asthe loading piston. The trap 220 captures perfume from the perfumed airthat is expelled from the container 10. The mass of expelled perfumecaptured by the trap 220 is determined using a GC/FID-MS (Agilent 6890and 5973 MSD) with a thermal desorption unit (Gerstel MPS2).

The analytical standard used is the Fragrance Materials Test Mix, Restekpart #31807, consisting of benzoic acid 1.0%, benzyl salicylate 36.2%,1.8 cineole 0.5%, trans cinnamaldehyde 0.5%, cinamyl acetate 0.3%,cinnamyl alcohol 0.3%, ethyl butyrate 36.2%, geraniol 0.6%,hydroxycitronellal 5.0%, d-limonene 20.0%, thymol 0.3%, and vanillin0.1% prepared in methanol (Standard Solution). The Standard Solution isthen diluted to 3 concentrations ranging from 0.25 g/L to 0.025 g/L.Standard solutions are then analyzed by GC/MS-FID. The amount injectedon column and the sum of the FID area responses are utilized to createthe calibration plot with a linear fit. Perfume components released fromthe package are identified by MS. Quantification is performed by the sumof the FID area responses of perfume components and the linear equationof the calibration plot. The mass of individual perfume components ofthe perfume expelled from the container 10 through the vent opening 100or vent openings 100 that occur in a quantity greater than 0.1 ng isdetermined and sum of the mass of each of these individual perfumecomponents is determined to be the mass of perfume expelled.

Without being bound by theory, it is believed that the mass of perfumeof expelled can be greater than about 1 ng when the Perfume ExpulsionTest Method is conducted on the container 10 so that a consumer is ableto ascertain the scent of the laundry scent additive 40 without openingthe package 10 by squeezing the package 5 by hand and expelling perfumedair from the within the container 10 out through the vent opening 100 orvent openings 100. Without being bound by theory, it is believed thatthe mass of perfume expelled can be greater than about 4 ng when thePerfume Expulsion Test Method is conducted on the container 10 so that aconsumer is able to ascertain the scent of the laundry scent additive 40without opening the package 10 by squeezing the package 5 by hand andexpelling perfumed air from the within the container 10 out through thevent opening 100 or vent openings 100.
